WILLIAM F. WE'GNER, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO HARRY H.CHIPPS, OF NEW YORK, N. Y.

ROTARY BRUSH.

Specification of Letters Patent.

Patented May 18, 1909.

To all whom it may concern:

Be it known tliat I, WILLIAM F. WEGNER, a citizen of the United States,and resident of the borough of Manhattan, in the city and State of NewYork, have invented a new and useful Improvement in Rotary Brushes, ofwhich the following is a specification.

The-object of my invention is to provide a ortable motor-driven rotarybrush having a ihn driven by the motor arranged to suck the dust anddirt into a receptacle from which the accumulated dust and dirt may beremoved at leasure.

Practica embodiments of my invention are represented in the accompanyingdrawin s in which,

igure lrepresents one form of the rotary brush in top plan, anintermediate ortion of the receptacle being broken away; ig. 2 is a sideview of the same, Fig. 3 is a ongitudinal central section taken in theplane of the line AA of Fig. 1, looking in-the direction of the arrows;Fig. 4 is a partial outside view of a second form of rotary brush; Fig.4 is a partial outside view of another portion of the same, showing themeans for closing the receptacle, Fig. 5 is a front end view of thebrush, and Fig. 6 is a section taken in the plane of the line BB of Fig.4.

In the form shown in Figs. 1 to 3 inclusive, the cylindrical bodyportion of the brush casing is denoted by 1,'from which extends aconical ortion 2 arranged to partially surround t e tapered rotary brush3, leaving a portion of the same exposed for contact with the surface tobe engaged by the brush. A handle 4 is provided. A receptacle 5 forreceiving thedust and dirt from the brush is removably secured to therear end of the cylindrical portion 1 of the casing, in the presentinstance by means of a clam ing ring 6 having its ends engaged by a olt7 andthumb nut 8. The electric motor is denoted by 9 and is rigidlyclamped in a frame 10 within the casing with its shaft 11 in alinementwith and secured to the stock 12 of the tapered brush, in the presentinstance by a cross pin 13. Intermediate the brush stock and the motorcasing, I provide a suction fan 14 the blades of which are arranged insuch a direction that when the fan and brush are rotated by the -motor,the dust and dirt swept up by the brush will be sucked into the casingand forced rearwardly intothe recep:

tacle 5. This receptacle 5 is made of some porous material such forinstance, as cheesecloth so as to ermit the escape of the airtherethrough without ermitting the escape of the dust and dirt. he wiresfor controlling the operation of the motor may be laid into the handle,as shown at 15, and the usual switch button 16 may be provided withineasy reach of the operator.

In the form shown in Figs. 4 to 6 inclusive, the electric motor 17,which is clam ed rigidly to its frame 18 within the casing, as securedthereto a ole handle 19 of considerable length. Thls pole is preferablyremovably secured by providlng a thumb screw 20 which passes through asocket 21 carried by the motor and a socket 22 carried by the polehandle. In this form the wires for controlling the operationof the motormay pass along within the pole handle 19, as shown. The receptacle 23for the dust and dirt is made of some flexible porous material, such forinstance, as cheesecloth, and

is, in this instance, permanently secured to,

the casing 24 by a ring 25 and its rear end may be closed b a suitablecord 26 arranged to fasten the en of the flexible porous rece taclesnuglyaround the pole handle 19: n

this form the casing 24 is of slightly tapered form and is provided atits front end with a yielding ring 27 of rubber or other suitablematerial. The brush 28 in this form is arranged with its bristlesprojecting from arms radiating from the shank 29 of the brush which issecured to rotate with the motor shaft and the rotary fan 30. Theoperation of the fan in this rotary brush is the same as in the firstform described in that it sucks the dust and dirt raised by the brushinto the casing and forces it past the motor into the flexible porousreceptacle 23.

What I claim is:

1. In an article of the character described, a casing, a motor rigidlysupported therein, a rotary brush anda rotary fan both carried by themotor shaft, andv a dust and dirt receiving receptacle secured to thecasing.

2. In an article of the character described, a casing, a motor rigidlysupported therein, a rotary brush and a rotary fan both carried by themotor shaft and a dust and dirt receiving receptacle of porous materialsecured to the casing.

-3. In' an article of the character described,

a casing, a. motor rigidly surfiported therein presence of twowitnesses, this fourteenth a rotary brush and a, rotary an both csrrie'day of May, 1908. by the motor shaft and a. dust and dirt receiving reoetacle of porous material remov- A WEGNER' 5 abl secure to the oasinWitnesses:
